The National Highway Traffic Safety Administration has announced recall campaigns for the 2011 Chevrolet Colorado and GMC Canyon, which may have faulty transmission position indicators. NHTSA also announced the recall of several GMT900 trucks which may have loose steering-shaft bolts; the issue affects the 2011 Cadillac Escalade; Chevrolet Silverado, Suburban, and Tahoe; and GMC Yukon and Sierra.

The Problem: A clip that holds the automatic transmission shift cable in place may not hold the cable correctly. In this case, the transmission position displayed in the "PRNDL" display may not reflect the transmission's actual gear selection. This means, for instance, a driver may mistakenly leave the vehicle in reverse or neutral instead of park, allowing it to roll away unexpectedly.

The Problem: A number of vehicles built on the General Motors GTM900 platform may have steering bolts that were incorrectly tightened. Because the bolts weren't tightened properly during vehicle assembly, they could allow steering components to separate while driving, causing a loss of vehicle control.

The Fix: General Motors will inspect affected vehicles to ensure that bolts are adequately tightened. The recall work should begin July 13.
